Preparing to Restore UFS Files and File
Systems

The ufsrestore command copies files to disk, relative to the current
working directory, from backups that were created by using the ufsdump command.
You can use the ufsrestore command to reload an entire
file system hierarchy from a level 0 dump and incremental dumps that follow
it. You can also use this command to restore one or more single files from
any backup tape. If you run the ufsrestore command as superuser,
files are restored with their original owner, last modification time, and
mode (permissions).

Before you start to restore files or file systems, you need to know
the following:

The tapes (or diskettes) you need to restore from

The raw device name on which you want to restore the file
system

The type of tape device you will use

The device name (local or remote) for the tape device

Determining the UFS File System Name

If you have properly labeled your backup tapes, you should be able to
use the file system name (/dev/rdsk/device-name) from the tape label. For more information, see How to Find UFS File System Names.

Determining the Type of Tape Device
You Need

You must use a tape device that is compatible with the backup media
to restore the files. The format of the backup media determines which drive
you must use to restore files. For example, if your backup media is 8-mm tape,
you must use an 8-mm tape device to restore the files.

Determining the Tape Device Name

You might have
specified the tape device name (/dev/rmt/n)
as part of the backup tape label information. If you are using the same drive
to restore a backup tape, you can use the device name from the label. For
more information on media devices and device names, see Chapter 29, Managing Tape Drives (Tasks).
